不知道哪里出错了
int one = 10 ;

int three = 0 ;
three=one﹢two;
System.out.println("three=one﹢two==>"﹢three);
three﹢=one;
System.out.println("three﹢=one==>"﹢three);
three﹣=one;
System.out.println("three﹣=one==>"﹢three);
three*=one;
System.out.println("three*=one==>"﹢three);
three/=one;
System.out.println("three/=one==>"﹢three);
three%=one;
System.out.println("three%=one==>"﹢three);
